How can I get rid of Windows Update reboot prompt?
I want Windows Update to automatically download and install updates on my Vista machine, however I don't want to be bothered by the system tray reboot prompts (which can, at best, only be postponed by 4 hours).
I have performed the registry hack described here to prevent Windows forcibly rebooting my machine, which is a good start. However, is there any way to get rid of the reboot prompts altogether, or decrease their frequency?
Answer
Not sure if it is the same for vista, but worth a try.
On Windows XP, you can modify a group policy setting to change how frequently it re-prompts you. (start -> run type gpedit.msc)
Look under Computer Configuration/Administrative Templates/Windows Components/Windows Update
The setting you want is called Re-Prompt for restart with scheduled installations. The default is 10 minutes.
You can also try modifying the No auto-restart for scheduled Automatic Updates installations setting found in the same location.
